Spacemen Prefer Blondes

When an extraterrestrial scout ship intercepts a shipment of cloned celebrities bound for Mars, the aliens sample the cargo and find sex with earth women to be out of this world. After developing an addiction to blondes, the crew persuade their captain to change their itinerary to include a field expedition to Earth. All in the name of science, he drops them off in San Francisco, aka Babylon by the Bay, where he expects they'll find something for every taste, no matter how alien.
